Description

Dron {A dron}

The present invention relates to a dron, and more particularly, to a dron which adopts a low center of gravity structure and is excellent in flying balance and is protected from an external impact.

Generally, Dron is a unmanned aerial vehicle that can be controlled by using radio waves. It is used in various fields because it is easy to carry, quick and economical. The drones are equipped with a camera, a sensor, a communication system, and perform various functions while flying. However, since the drone performs the function by flying, there is a high possibility of a fall due to changes in the external environment such as wind speed and wind direction, and immaturity of driving operation. In addition, expensive parts such as cameras and systems mounted on the main body can be damaged during the fall, which can cause damage to the data, causing damage to the components and causing economic damage. Therefore, a drone is required to prevent damage to the fall.

Korean Patent Registration No. 10-1496892 is disclosed as a technique for the above-described drones.

However, the above-mentioned drones judge the fall of the dron and make an emergency landing through the parachute to prevent breakage. Therefore, there is a problem in that, in addition to the fall, it may be damaged when suddenly colliding with a branch or the like. Also, there may be a limitation in the function due to the mistaken decision to fall into motion caused by a sudden weather problem.

The drones must perform various functions smoothly in flight, so it is important to maintain the flight even though it is affected by the constantly changing weather conditions. do.
